Abstract
Electrical conductivity, transport number, and density measurements on solutions of some simple bases, including alkali metal and alkaline earth metal chlorosulfates, are reported in the chlorosulfuric acid solvent system. The SO3Cl− ion was found to have a high mobility compared with, for example, the mobilities of the alkali metal and alkaline earth metal cations, and is believed to conduct by an abnormal Grotthus-type chain mechanism. Alkali metal chlorosulfates appear to behave as fully dissociated electrolytes, whereas alkaline earth metal chlorosulfates are incompletely dissociated. Difficulties encountered in preparing pure chlorosulfuric acid are discussed.Keywords
